Temporal feels massive, I tried it for a small workflow embedded on my system, and worked fine, but when thinking on scaling it, it just didn't made any sense for my use case.

I also have restate.dev on my reseearch list, which on paper should scale well and be definitely more lightweight and simple to setup, worth having a look.

26 years building production systems across founding teams and scale-stage operations. Founding engineer 3x. Shipped a Go service handling 100k messages/sec on distributed identity. Led the team of five that built ernest.io — open-source IaC.

For the last 18 months I've been running a structured AI workflow in production — plan→work→QA loop, specialist agents, overnight batch runs. Documented at https://adriacidre.com/.

Open to senior IC, AI platform, or harness-engineering work at small teams where engineers own the product end-to-end. Stack-agnostic — the company picks; I adapt.

Author here. Worth flagging: this pays back because public hospital reports use the same handful of layouts for years. For a long tail of one-off document types, vision is probably the right call — the parser write cost wouldn't amortize.
